2012 Lexus RX 450h To Geneva: What Would You Like To Know?

Physically small in size, it's nevertheless one of the biggest events on the motoring calendar and the scene of major launches every year.

This year, Lexus is lending us an example of its premium hybrid off-roader, the 2012 Lexus RX 450h. We'll be driving it down from the U.K. in the middle of the night, on an 800-mile trip to Geneva, and once the show is over, driving it another 800 miles back.

That's plenty of time to get a feel for the car, so we're asking you - what would you like to know?

A facelifted version of the RX will be unveiled at Geneva, and while the re-style will bring it more in-line with some of Lexus' more recent vehicles, it should be mechanically similar to our test vehicle.

For the all-wheel-drive model, that means 30 MPG in the city, 28 MPG on the highway and 29 MPG combined. Driving around Geneva itself should allow us to test the hybrid system to the full too, so it won't all be highway mileage.

So what would you like to know about the Lexus luxury off-roader? Whether it's practicality, real-world economy, noise or performance, we can find out for you in our week with the car.
